Precision Kelvin Bridge (EE - 525)

The bridge is capable of measuring resistance from 10 to 1 ohm. 10 coils, of 0.1 ohm are arranged on a rotary dial. A slide wire reads resistance in steps of 0.001 ohm. The bridge is provided with a multiple of 0.1, thus enabling he bridge to be used for measurement up to 0.0001 ohm. Separate current and potential terminals are provided. Coils are of double Eureka wire and are all properly aged. All coils are calibrated on imported testing bridge. Accuracy of adjustment is ±0.1%.
